Castrol GTX uoa or voa

Anyone have a uoa or voa of this oil? The new formula.

I have a uoa of the previous formula in case you're interested. I did a 3000 mile uoa of GTX 20W50 on my 300ZX. I'm wondering if it was the new formula packaged in leftover previous jugs,because it had moly,which I believe GTX never had previously. But I may be wrong.

The PQIA Has VOAs on GTX, I believe in 5w20 & 5w30.

They both look like good oils to me. Decent low Noack for a conventional oil (the new GTX Ultraclean is semi-synthetics now days). Plus a nice add pack, in round figures it looks roughly like almost 100ppm Moly and 200ppm Boron (rounding up).

Regular Ca detergent package, so maybe not first pick for DI with LSPI issues, but a good TBN of just over 8.

It's the Noack volatility that impressed me most, as I've seen some 5W30 oils sail very close to the upper API SN limit of 15%, while the GTX is showing under 13% which would meet the higher quality requirements of Dexos or ACEA.

The above VOA's are for the North American GTX, I'm running the Australian version GTX UltraClean 15W40 (SN & A3/B3) myself right now.

Thanks all. Always liked Castrol but, was curious what the gtx was these days as I have used Valvoline for almost 10 years.
